With the increasing consumption and decreasing reserves of fossil fuels, the resources will be exhausted in the whole day, and a new energy-containing body energy source which is independent of fossil fuels and rich in reserves is urgently needed to be searched.

At present, offshore culture systems are mostly arranged in coastal shallow sea water areas, most of which have the water depth of less than 20 meters, and have the problems of single culture variety, high culture density, frequent disease occurrence, environmental deterioration and the like. The seawater quality of the medium-deep water area of 20-40 meters is better, and the cultivated fish species are more and far away from the continent, so that floating and mobile marine cultivation become a direction for the development of the aquatic cultivation industry, such as High Density Polyethylene (HDPE) gravity type net cage preparation, large steel structure semi-submersible type net cages, cultivation ships and the like. The HDPE net cage occupies a dominant position due to low price, but the strength and fatigue resistance of the HDPE net cage are outstanding, and the HDPE net cage is particularly not suitable for severe sea conditions such as typhoons.
With the vigorous development of offshore wind power plants, the local consumption of unstable wind power becomes an issue, and offshore wind power hydrogen production is a breakthrough direction in europe and China, but how to achieve economic benefits is yet to be further verified. Considering that the fishery breeding return rate is high, if the fishery breeding and the marine hydrogen production can be combined together, the economic benefit is expected to be improved, so that the key is to organically combine the fishery breeding and the marine hydrogen production, and no equipment for integrating the fishery breeding and the marine hydrogen production exists in the world at present.
